Title: Flaw erasing agent for photography and flaw erasing method therefor
Inventor: TAMURA YUTAKA
IPC: G03C11/06
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To obtain a flaw erasing agent for photography which is easy to handle and has a high flaw erasing effect by using liquid having a specific refractive index and specific viscosity. SOLUTION: This flaw erasing agent consists of the liquid having the refractive index of 1.5 to 1.8 and viscosity of 0.1 to 100cps. The liquid viscosity is more preferably 0.5 to 70cps. The liquid having such viscosity may be prepd. by using a soln. compd. having such viscosity or by mixing a soln. compd. having a high viscosity and a soln. compd. having a low viscosity. The adjustment of the viscosity by addition of a surfactant is equally preferable. The more particularly preferable surfactant is a fluorine surfactant. The refractive index is preferably 1.54 to 1.78. The reason thereof lies in that such surfactant has an effect of making the flaws hardly visible even if air remains deep in the flaws. Namely, the refractive index is preferably set equal to or slightly higher than the average refractive index of the blanks, cellulose triacetate, etc., used for a photographic base.

Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To save space so as to enhance an effect by providing a flare diaphragm member capable of moving in an optical axis direction, an energizing means energizing the flare diaphragm member in the optical axis direction and an abutting part regulating the position of the flare diaphragm member in the optical axis direction. SOLUTION: The projection part 12a of the flare diaphragm 12 is energized to a front side by an energizing spring 13, so that it can be moved to a position where it abuts on a front side stepped part 14b being the regulation part of a supporting shaft 14. The projection parts 12a and 12b of the diaphragm 12 shield light so that the shaft 14 and the spring 13 may not be irradiated with the light beam, and formed so that they may abut on the projection part 8e of a three-group frame 8 at a specified position in zooming. Space for a cam ring is required in a device driven by the cam, but it is not required in this case, so that the lens barrel is constituted with the small space. Besides, the stop position of the diaphragm 12 is set at the most effective position, so that the harmful light is efficiently cut.

Title: Power turbine power transmission mechanism and turbo-compound system
Inventor: NEMOTO ISAMU
IPC: F02C6/00
Filed: 1984-05-15
Abstract: PURPOSE:To prevent a shaft output from being adversely transmitted to a power turbine side by installing a one-way clutch midway in the power transmitting mechanism of a captioned device in which the driving force of a power turbine whose driving source is the exhaust gas of an engine, is transmitted to the output shaft of said engine. CONSTITUTION:The exhaust gas of an engine E drives a turbocharger TC to carry out supercharging, while also drives a power turbine PT which is installed in an exhaust bypass D which bypasses the turbine of the turbocharger TC and is opened and closed by a waist gate valve WV. The driving force of the power turbine PT is transmitted to an engine output shaft ES via gears 1, 2, fluid clutch FC, and gears 3-6. The final driven gear 6 of a power turbine reduction gear train is combined with the output shaft ES through a one-way clutch 7 which allows free rotation only in the adverse direction to the rotation direction of the output shaft ES. Thereby, the shaft output can be prevented from being adversely transmitted to a power turbine driving system.

Title: Lead battery
Inventor: KAWANAMI YOSHIHARU
IPC: H01M50/437
Filed: 1982-06-03
Abstract: PURPOSE:To achieve excellent high rate discharge performance by employing a separator composed of short glass fiber having average diameter shorter than 1.0mu and a sheet composed of long glass fiber having average diameter longer than 1.0mu pressed on both faces of positive and negative plates. CONSTITUTION:In a retainer lead battery having nominal capacity of (20hR) 7Ah, short glass fiber having average diameter of 0.6mu is employed for the separator while sheets of 0.2mm. thickness composed of long glass fiber having average diameter of 9.0mu pressed on both sides of each plate are employed for filling the positive and negative plates with paste and performed high rate discharge of 35A resulting in the discharge capacity of 2.7A or the fifth second terminal voltage of 1.77V. The reason for employing the long fiber having average diameter longer than 1.0mu as the glass fiber to be pressed on the plate is that when the sheet is pressed on the surface of the plate and covered over the entire face of the plate, the reaction product between the electrolyte and the active substance or the sulfate is hard to be produced during discharge to suppress the discharge thereby the rough press sheet is preferable and it is hard to achieve that state with short and thin fiber.

Title: Optical fiber identification method for optical line
Inventor: SHIGEMATSU MASAYUKI
IPC: H04B10/079
Filed: 1987-04-17
Abstract: PURPOSE:To securely identify an optical fiber during the transmission of a light signal by bending the fiber to be identified or another fiber on the upstream side of a light signal and causing an increase or decrease of emission loss light at the bent part on a downstream side, and observing it. CONSTITUTION:Bent parts 25a and 25b of both fibers 5a and 5b are formed on the side of a relay part 14 and emission loss light rays from them are detected by photodetecting elements 45a and 45b. The the fiber 5a to be identified is bent on the upstream side of the light signal on the side of the relay signal 13 to form a bent part 15a, generating emitted loss light. When the emitted loss light on the downstream side is detected in this state, the emission loss light level of the bent part 25a drops, so the fiber 5a can be identified. In this case, the upstream and downstream bent parts only generate emission loss light rays and are therefore made large in radius of curvature. Consequently, the quantity deterioration of an optical communication signal, the cracking and breaking of a fiber are prevented.

Title: Magnetic recording medium and production thereof
Inventor: MIZUNO CHIAKI
IPC: G11B5/716
Filed: 1988-04-19
Abstract: PURPOSE:To improve surface smoothness and to maintain a high residual magnetic flux density by incorporating cobalt-contg. iron oxide as a ferromagnetic material into two upper and lower magnetic layers and giving specific conditions to the residual magnetic flux densities of the two magnetic layers. CONSTITUTION:The magnetic layers contain the cobalt-contg. iron oxide as the ferromagnetic material. The magnetic layers are so formed that the ratio Br1/Br2 between the residual magnetic flux density Br1 of the upper magnetic layer and the residual magnetic flux density Br2 of the lower magnetic layer is >=1,600 gauss. The residual magnetic flux density of the upper magnetic layer is, therefore, assured and since the lower magnetic layer has the residual magnetic flux density lower than the residual magnetic flux density of the upper layer, the layer surface has the smoothness. The surface smoothness of the upper magnetic layer is imparted to said layer as well. Namely, the surface smoothness is assured if the magnetic layer having the high residual magnetic flux density is formed on the magnetic layer having the high smoothness.

Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a lead frame for a semiconductor device having a black oxidation film of copper, which sticks well to sealing resin on the surface of non-copper base material. SOLUTION: A copper-plated layer 10 is formed on a plane, where a lead frame 1 comprising non-copper base material 2 is bonded to a sealing resin 9, and a black oxidation film of copper 11 is formed on the surface of the copper-plated layer 10. Since the black oxidation film of copper 11 has a feather- like rough surface, the sealing resin penetrates the film 11 to bond thereto firmly. Since the copper-plated layer 10 remains under the black oxidation film 11, the sealing resin firmly joints to the non-copper base material 2. To form the black oxidation film 11, a surface treatment method by which the copper-plated layer 10 of the lead frame 1 is anodized in an organoalkali solution is adopted. Since the organoalkali solution does not contain a metal, no metal remains on the black oxidation film 11 after it is rinsed.
